same error, have you resolved it ?

Hey, I'm trying to call https://api.searchads.apple.com/api/v5/reports/campaigns using the jwt token created by myself, but getting the following response: response, code: 401, body: {"data":null,"pagination":null,"error":{"errors":[{"messageCode":"UNAUTHORIZED","message":"Invalid token: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx","field":""}]}}. Have you met this situation? If true, can you share with me how to resolve it?
